Operation Brock has been reintroduced on the M20 in Kent, with the temporary lorry park at Manston Airport closing on Saturday night.
It marks a new stage in post-Brexit arrangements for hauliers, but how will it affect our roads?
The new measures were introduced at 4am on Sunday, with Eurotunnel and Port of Dover freight being directed into separate lanes.
The barrier, London-bound, is still in place with traffic still using a contraflow system.
Any hauliers without a Kent Access Pass or a negative Covid certificate are being directed to the new Sevington Inland Border Facility.
